This part of ISO 10426 specifies requirements and gives recommendations for eight classes of well cements,
including their chemical and physical requirements and procedures for physical testing.
This part of ISO 10426 is applicable to well cement classes A, B, C, D, E and F, which are the products
obtained by grinding Portland cement clinker and, if needed, calcium sulfate as an interground additive.
Processing additives can be used in the manufacture of cement of these classes. Suitable set-modifying
agents can be interground or blended during manufacture of classes D, E and F.
This part of ISO 10426 is also applicable to well cement classes G and H, which are the products obtained by
grinding Portland cement clinker with no additives other than calcium sulfate or water.
